Title: Improvements in and relating to shoes for personal wear
IPC: A43B3/10
Filed: 1925-01-26
Abstract: 228,534. Swanson, J. E. Jan. 25, 1924, [Convention date]. Stiffeners; uppers; fastening; slippers. - A shoe having an upper the quarters of which overlap at the heel to accommodate a counterstiffener, as described in Specification 25055/99, is characterized in that the overlapping parts form a pocket as hereinafter set forth into which the counter-stiffener is inserted and secured by the upper being lasted-in beneath it. The invention is shown applied to a moccasin but is not limited thereto. Blanks, Figs. 3 and 4, are made with similarly curved ends 15, 19 which overlap and are secured by stitching 23, 25, Fig. 1, symmetrical with a centre line 17. In order to form a pocket, the edge 19 is cut further from the centre line 17 than the edge 15, and as the stitching 25 progresses the edge 19 is drawn inwards towards the centre line. The stitching 23, 25 simulates an ornamental backstay. A counter-stiffener 26, Fig. 2, is inserted from beneath into the pocket between the overlapping ends and the upper lasted-in beneath it and secured to a slip sole 27 to which an outer sole 28 is afterwards attached. The blank 1 for the moccasin is heart-shaped with an incision 3, the edges of which are sewn together. An edge 14 of the blank shown in Fig. 4 is attached to an edge 7 of the blank shown in Fig. 3. In this way the insole of the mocassin is formed by part of the blank 1, the remaining part forming a portion of the upper including the upstanding front portion. The moccasin is completed by an insert 30 with an integral tongue 32. Strap fastenings are added.

Title: Improvements in or relating to electric obstacle location systems
IPC: G01S1/02
Filed: 1944-02-07
Abstract: 592,616. Radiolocation. STANDARD TELEPHONES & CABLES, Ltd. Feb. 7, 1944, No. 2275. Convention date, Sept. 14, 1942. [Class 40 (v)] In a pulse operated distance indicating system the receiver is normally blocked and is only operative to pass signals to an indicator when the signals coincide with a control voltage pulse applied to the receiver, the timing of the applied pulse with respect to the transmitted pulse being a measure of the range of the object producing the signal. A pulse generator 13, Fig. 1, controls a transmitter 12 which radiates pulses 58, Fig. 4a, from antenna 14, and also synchronises a multivibrator 11 producing a wave 65, Fig. 4b. The wave 65 actuates a sweep generator 10 producing a sweep voltage such as A or B, Fig. 4c, which is applied to a variable bias control circuit 16 comprising a valve, Fig. 2 (not shown) with a controlled bias applied to its cathode from a potential divider. When the applied sweep voltage exceeds the controlled bias the valve is rendered conducting and produces a constant amplitude pulse the timing of the leading edge of which is determined by the controlled bias voltage and the slope of the sweep voltage. The leading edge of the pulse can thus, by adjustment of the bias control, and selection of the sweep voltage which may correspond to short or long ranges, be timed to coincide with an echo signal such as 62 or 64. The pulse is passed through a shaping circuit 20 and the resultant pulse such as 78 or 80, Fig. 4d, is applied to a variable resistance-condenser differentiating circuit 22 which produces a narrow pulse such as 82 or 84, Fig. 4e, which is of just insufficient amplitude to unblock the amplifier 26 following the receiving antenna 30 and receiver 32. If, however, the pulse coincides with a received signal such as 62 or 64, the combined effect is sufficient to unblock the amplifier 26 and permit an output to be obtained from indicator 34, and the adjustment of the bias control indicates (scales A or B<1>, Fig. 4c), the range of the received signal. The variable differentiating circuit may be adjusted to produce pulses covering only short range intervals, or pulses such as 85 which cover long intervals, possibly from a fixed range out to the maximum range, so that an indication, which may be audible, will be given of objects beyond the fixed range. It is stated that as an alternative to a predetermined voltage sweep and a variable bias, a fixed bias and a controllable voltage sweep may be employed for producing the variably timed pulse.

Filed: 1941-02-20
Abstract: 547,294. Coating with adhesives. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Feb. 20, 1941, No. 2312. [Class 95] [Also in Group VIII] A machine for folding the marginal portions of sheet material, e.g. for folding French binding around the edge of a shoe upper, is provided with means for delivering thermoplastic adhesive in heated condition to the workpiece as it is being operated upon to secure in position the folded portion. Successive edge portions of the workpiece are turned upwardly against a creaser foot 22 by an oscillatory folding finger 20, and the folded portion is pressed against the body portion by a hammer 26 and anvil 28. The work may be clamped against the foot 22 by a gripper member 24 operated as described in Specification 208,217, [Class 42 (i)]. The adhesive is supplied to the work through a passage 156 in the creasing foot 22 from a reservoir 182. The reservoir, the foot 22, and the connections between these parts are heated electrically. The heating of these elements may be varied by adjusting a rheostat, and the temperature of the foot is indicated by a thermometer 411. The adhesive is delivered by a pump 180 arranged within the bottom of the reservoir, and comprising a slidable sleeve 206 and plunger 210. Ports 212 spaced 180 degrees apart are provided in the sleeve 206, one port providing communication from the reservoir to an intake port 214 in a second sleeve and serving as a valve controlling the. flow of adhesive. The sleeve 216 is arranged to be rotated to open and close the port 214 upon energisation of a solenoid 290. A plunger having markings upon it or other device may be provided for indicating whether the port 214 is open or closed. Means are provided for varying the effective stroke of the pump to vary the amount of adhesive delivered to the workpiece. Heat radiating ribs are arranged to extend partly across the reservoir, and a bellow-form thermostat is connected to a bulb 192 arranged below the heating element 188 for the reservoir so as to operate a switch to control the supply of current to the heater. The position of the edge of a workpiece is determined by a gauge finger 30. When folding joints between overlapping ends, or at sharp corners, the workpiece may be manually presented to an adhesive-applying roll supplied with heated adhesive.

Filed: 1918-02-09
Abstract: 122,914. Efandem Co., and Williams, A. H. Feb. 9, 1918. Battery lamps.-In battery lamps of the kind which are carried by a handle which projects therefrom, for example a bar handle, the switch or a part thereof, is carried by the handle so that the circuit may be opened and closed by the hand which carries the lamp. In the construction shown, the switch, which is of the form described in Specification 122,511, [Class 38 (v), Electric switches &c.], is carried entirely by the handle, which consists of a metal tube B carried from the casing by brackets C, C'. The bracket C' is electrically connected with the tube through the metal washer k whereas the bracket C is insulated therefrom by washers e and connected with the pin D the conical head d of which constitutes the fixed contact of the switch. The movable contact-member has a split cylindrical part p which takes a spring fit within the tube and a tongue portion p<2> fitted with a press-button p<3> projecting outside the tube. Temporary contact is made by pressing the button inwardly, and permanent contact may be secured by sliding the contact member so that the tongue wedges on to the fixed conical contact. The contact-member may be moved back so far that on pressing the button, no contact is made. In a modified form of this construction, the tube B is supported on tubular standards within which posts, equivalent to the brackets C, C', are arranged, one of the posts being insulated from its standard so that the circuit cannot be completed by accidentally bridging the standard by a conductor. In a further modification, a sliding contact-member on the metal handle (which is divided into two parts separated by insulating- material) may be moved by the hand carrying the lamp so as to bridge the two parts of the handle.

Title: Improvements in or relating to facsimile recorders or scanners
Inventor: HESTER FRANK ALLEN
IPC: H04N1/16
Filed: 1952-02-01
Abstract: 720,557. Copying-telegraphy; television. FAXIMILE, Inc. Feb. 1, 1952, No. 2709/52. Drawings to Specification. Class 40 (3). A picture-transmission system comprises a scanner or recorder provided with scanning or recording means including a linear means and a co-operating rotatable helical means intersecting said linear means at an angle of at least 45 degrees to define therewith a substantially parallelogrammatic area of intersection, the widths of the intersecting linear and helical elements being proportioned to provide substantially equal resolution or definition in the direction of the linear means and at right angles thereto. The angle of intersection is preferably greater than 45 degrees and less than 75 degrees, and the parallelogrammatic area is joined by the intersection of linear electrode or slot and a helical electrode or slot respectively. The ratio of horizontal to vertical definition is defined in terms of a formula involving the angle (#) of intersection and the ratio of the actual or effective widths of the linear and helical means and it is shown that to obtain definition as good in the horizontal direction as that in the vertical direction, the angle # must be equal to or greater than 45 degrees. The Spcification includes curves showing the relation between marking a response efficiency, the angle #, and the relative widths of the co-operating elements, and in addition, families of curves relating marking efficiency, 6 and the ratio of horizontal to vertical definition. It is indicated how the angle 6, i.e. the relative length and diameter of a drum carrying one turn of a spindle electrode, can be selected for a given ratio of horizontal to vertical definition, with an acceptable or desired figure for the marking efficiency. The formula referred to is derived from principles set out on p. 485 of the Bell System Technical Journal of July 1934.

Title: Improvements in or relating to the production of hydrogen peroxide
Inventor: SPRAUER JEROME WILLIAM
IPC: C01B15/023
Filed: 1956-01-27
Abstract: A degraded solution of an alkyl anthraquinone in a solvent, which has become degraded in the process for synthesizing hydrogen peroxide involving alternately hydrogenating the alkyl anthraquinone and oxygenating the resulting alky anthrahydroquinone which is recycled after separation of the simultaneously formed hydrogen peroxide, is regenerated by heating the degraded solution at at least 55 DEG  C. in the presence of activated alumina or active magnesia.  Activated alumina is microporous alumina of extensive surface area obtained by heating, e.g. at 300-800 DEG  C., natural or synthetic hydrated alumina, which may or may not contain a minor proportion of silica, to convert it to a less-hydrated form, e.g. a -alumina monohydrate, or g -alumina.  Active magnesia is anhydrous microporous magnesia of extensive surface area obtained by decomposing magnesium hydroxide, carbonate, or nitrate.  The alumina or magnesia adsorbs the organic degradation products and catalyses the regeneration, and is preferably granular, e.g. 4-100 mesh.  The adsorption may be effected at 55-300 DEG  C., preferably 90-150 DEG  C., and the adsorbent may be in amount at least 0.5 per cent, usually 5-10 per cent.  The spent adsorbent may be revivified by extracting with an organic solvent. Preferred revivification is by successive treatments with heptane, methanol, hydrochloric acid solution in aqueous methanol, water, dilute aqueous alkali, e.g. 0.1N caustic soda, and water.  The adsorbent is finally dried at 100-110 DEG  C.  Alkyl anthraquinones may be ethyl-, methyl-, propyl-, or isopropyl-anthraquinones, and solvents may be mixtures of benzene and higher alcohols, but exemplified is a solution of 2-t-butylanthraquinone in a mixture of 1-methyl naphthalene and diisobutyl carbinol.  The alumina or magnesia contact may be batch or continuous in a column.  It is preferred to treat continuously a portion, e.g. 10 per cent, of the recycle from the extractor to the hydrogenator.  When the solvent contains both an alcohol constituent and a hydrocarbon constituent, the regeneration is effected on a solution from which the alcohol has been distilled, and the alcohol constituent is added after treatment. The activated alumina may have palladium deposited thereon.  It is stated that silica gel, glass beads, corundum, magnesia obtained by burning magnesium in air, synthetic zeolite, and bone black are not effective in the regeneration.
